So far looks good, although the green text at the bottom of the level preview screen still looks blurry to me. Also, just wondering if this was intended.
Was it intended to remove the ability to left-click on empty space in the title screen in order to get to the level preview screen?
Yes, though undoing this is not out of the question.
In short - the code for the menu screens was, not completely rewritten from scratch, but pretty close. In particular, the code for handling mouse / keyboard input is completely replaced. Initially, I had only the clickable items (and keyboard shortcuts) on all screens. This felt awkward to me on the preview etc screen, so I restored it there, but it hasn't really bothered me on the title screen so I figured I'd leave it as is, rather than introducing an unexpected (to those not familiar with prior version behaviour) "click in empty space" behaviour.
I see. Yea, I would love to be able to continue clicking on empty space to go to the level preview screen, so when it didn't work anymore when I tried out the RC2 update it took me by surprise. I'm definitely used to it due to how I grew up with the Dos version of Lemmings since the behavior was present there. Besides that, one could also press F1, but I never did that. I generally use the mouse way more than the keyboard when I'm playing Lemmings. By the same argument, clicking on the level select menu card will be familiar to those who grew up with Lemmings on engines that only allowed you to click on the level select menu card on the title screen in order to get to the preview screen.
So really, if the clicking the empty space behavior to proceed was restored, then that would be the best of both worlds, as the ones who grew up with the Dos version will have the empty space behavior they're familiar with, while those who could only proceed by clicking on the level select menu card in other platforms can either continue to do so because it's familiar to them or they can occasionally use the empty space behavior to proceed because the option to do so is there as well. Of course, it shouldn't be brought back just because I want it. Instead, let's see if anyone else also wants the empty space behavior. Quite frankly, I've always felt clicking on empty space is much faster than clicking on the level select card. And I'm not saying that because I grew up with the former behavior.
I do want to make it clear that the green text on the preview screen is a very welcome addition, especially for those who are completely new to NL or who never ever played the game to make it easier for them to learn to play the game. Nevertheless, since I'm very used to clicking on empty space behavior, that's what I'm going to keep using to enter the level from the preview screen even though the option to click on "continue" at the bottom of the screen is there. In this case, I'm happy the behavior's still there on the preview screen. Now if it can be restored on the title screen as well, that would be awesome and would make me a happy camper. However, let's see if others agree, as it should be brought back only if there's much demand for it. The only other compelling reason I can think of to bring it back is that this is inconsistent, since it's enabled on the preview screen but not the title screen.
Finally, in case you haven't heard it from me enough, I appreciate all the maintenance and update work you been doing on NL and continuing to improve and make it wonderful.
